Election Winners: Which party won each constituency

The "Statistical atlas" lets you view our British statistical data rates
by theme in their entirety as maps for both modern local authorities and historical
units.

Please note that although there are some statistics within the system relating
to places outside Great Britain, particularly Ireland, the majority of our statistics
are British and this is reflected in the presentation of data within the Statistical
atlas.

How it works

The Statistical atlas presents national views of rates. This differs from the specific
numeric data for individual administrative units presented in the "Units & Statistics"
part of the place pages accessed via typing in a place-name on the homepage.

Select a theme by clicking on a theme title. You must then decide whether you wish to view
data for modern local authorities or historical units. At the top of the theme page are the links
to rate maps for modern units. Select one to enter the atlas. Alternatively, at the bottom of the
theme page are links to maps of rates only available in their historical units.

After selecting a rate we are presented with the map page showing the selected rate. On the
left hand side is the map legend and some generic subject information about the theme.
Below the text is a link to the "Rate definition" which takes you out of the statistical atlas
and into the description of the nCube for that theme within the data documentation system.

Beneath this are various "Options" for altering the mapped rate. With the exception of the
"Political Life" theme, drop down menus exist to change the mapped rate or to select an alternative
unit type. All themes have the option to select alternative dates. Selecting a different date will
change the map to display re-districted data i.e. statistics which are estimates for the same (modern)
geographical area going back over time. More information on how
this was achieved is available
here.

The map window on the right can be zoomed and panned. Using the drop down menu at the top left of
the map window you can select and add a "base layer" map image beneath the transparent statistical
map to help you understand the geography of the rates. The window itself can be expanded to see a
bigger map using the "Bigger map" option at the top right of the map window. If this function is
enabled, the information given on the left will automatically move to below the map.

About the data

The statistics come from national overviews, including Censuses, Surveys and other collated tables.
You should be aware that the same information was not always collected, the questions change over time
to suit contemporary conditions. For example, in the 2011 Census English households were asked about
their car ownership, but this would have been of little relevance in 1921 when very few people owned
their own vehicle. Conversely, the 1951 question about whether your household had shared access or no
access to piped water has disappeared because it is now assumed that all, or virtually all, households
will have exclusive use of a piped hot water supply. This is why not all themes have data in all years,
the dates available vary according to the questions asked.

We should also point out that we have not digitised all possible historical statistics. Although we
have gone a significant way to capturing and integrating suitable tables useful for our themes, this is
a labour intensive and time-consuming process. We have tried to focus on particular tables to produce
runs of data and in this sense the "Population" theme is the fullest. We continue to work on improving
the data, both in its consistency and its accuracy as well as its extent.
